Mullard Blackburn UK production !

This is a ECC82 produced by Mullard in1970 in Blackburn UK (version Gf2). The tube bears the Philips print. The tube has a ring getter on ‘copper’ post and ribbed grey plates, see pictures. Tube with balanced systems; see test results.


The overall sound character of British tubes is warm and lively with a very spacious soundstage. The top is silky soft and pleasant and does not roll off. They retain a nice sense of “air” at the top end, and the upper mids are smooth and fluid. This tube class reproduces the human voice, including female voices in complex choral pieces, with impressive realism. In addition, they are also known for rich bass. The Gf2 Mullard ECC82 fulfills the previous description very well. I refer to the many threads on the web for more information. Excellent preamp valve and because of the low noise level , very suitable in phono stages.

Note: if your system is “warm sounding’ or to “warm” already, this tube is not a first choice. ECC82 tubes of Philips, Valvo, Siemens or Telefunken are to be considered in that situation.
